voice_set_playmode(3alleg4) Allegro manual voice_set_playmode(3alleg4)NAME
voice_set_playmode - Adjusts the loop status of the specified voice. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void voice_set_playmode(int voice, int playmode);
DESCRIPTION
Adjusts the loop status of the specified voice. This can be done while the voice is playing, so you can start a sample in looped mode (hav-
ing set the loop start and end positions to the appropriate values), and then clear the loop flag when you want to end the sound, which
will cause it to continue past the loop end, play the subsequent part of the sample, and finish in the normal way. The mode parameter is a
bitfield containing the following values:
PLAYMODE_PLAY
Plays the sample a single time. This is the default if you don't set the loop flag.
PLAYMODE_LOOP
Loops repeatedly through the sample, jumping back to the loop start position upon reaching the loop end.
PLAYMODE_FORWARD
Plays the sample from beginning to end. This is the default if you don't set the backward flag.
PLAYMODE_BACKWARD
Reverses the direction of the sample. If you combine this with the loop flag, the sample jumps to the loop end position upon reaching the
loop start (ie. you do not need to reverse the loop start and end values when you play the sample in reverse).
PLAYMODE_BIDIR
When used in combination with the loop flag, causes the sample to change direction each time it reaches one of the loop points, so it
alternates between playing forwards and in reverse.

play_sample - Plays a sample. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int play_sample(const SAMPLE *spl, int vol, int pan, int freq, int loop);
DESCRIPTION
Triggers a sample at the specified volume, pan position, and frequency. The parameters `vol' and `pan' range from 0 (min/left) to 255
(max/right). Frequency is relative rather than absolute: 1000 represents the frequency that the sample was recorded at, 2000 is twice
this, etc. If `loop' is not zero, the sample will repeat until you call stop_sample(), and can be manipulated while it is playing by call-
ing adjust_sample(). Example:
/* Scream from the left speaker, twice the freq. */
int sound = play_sample(scream, 255, 0, 2000, 0);
RETURN VALUE
Returns the voice number that was allocated for the sample or negative if no voices were available.
